The present document applies to cooperative communications using radio transmitters and receivers for Intelligent Transport Systems (ITS). ITS communications may comprise vehicle-to-vehicle, vehicle-to-infrastructure and infrastructure-to-vehicle.
The equipment is comprised of a transmitter and associated encoder and modulator and/or a receiver and associated demodulator and decoder. The types of equipment covered by the present document are as follows:
• OnBoard Equipment (OBE) fitted with an integral or dedicated antenna(s), intended for use in vehicles, e.g. a road or a rail vehicle.
• RoadSide Equipment (RSE) fitted with an antenna socket, integral or dedicated antenna(s), normally used as a fixed station, e.g. a road or rail infrastructure.
These networks operate over a short range with very wideband communications using a variety of directional medium and high gain antennas to enable a high degree of spectrum reuse, and may use a flexible bandwidth scheme under which they normally operate in a wideband mode, and periodically reduce their bandwidth (e.g. for antenna training and other activities).
The technical characteristics of these applications are described in ETSI TR 102 400, where ITS applications in the 63,72 GHz to 65,88 GHz band is described. The present document is also in line with the results of the spectrum compatibility study in the CEPT ECC Report 113.
These radio equipment types are capable of operating in all or any part of the frequency bands given in table 1.
